I was required to update Anaconda and now when I try to connect sqlalchemy to my database I get the error above. The command I previously used is below
engine = create_engine('mssql+pyodbc://' + server + '/' + database + '?driver=SQL Server?Trusted_Connection=yes', echo = True)
I am very much a NOOB with all these connection issues and appreciate the help. How do I fix this? What other information do you need to help?

    You can use Anaconda Prompt to run cmd "conda install -c anaconda pyodbc" as admin and then run jupyter or python

    import pyodbc [x for x in pyodbc.drivers()]

    you will see 'SQL Server' in the result of the cmds and use "DRIVER={SQL Server};" for your DB connection

    Hi @Addie, Andrew ，

    First of all, it should be clear that this is a SQL Server forum, we are not familiar with sqlalchemy and cannot give help with it.

    Please check version of ODBC driver, not sure if the code you shown is complete, but you may need 'DRIVER={ODBC Driver 17 for SQL Server}' instead driver=SQL Server
